ENGINE-GOVERNOR.

A SPECIFICATION forming part of Letters Patent No. 780,429, datedJanuary 17, 1905. Continuation of application Serial No. 117,299, filedJuly 28, 1902. This application filed May 18, 1904. Serial No. 207,791.

To all whom, it may concern;

Be it known that I, JAMEs E. KIMBLE, a citi zen of the United States,residing at the village of Vicksburg, county of Kalamazoo, State ofMichigan, have invented certain new and useful Improvements inEngine-Governors, of which the following is a specification.

This invention relates to improvements in speed-regulating devices forengine-governors.

The objects of the invention will fully appear from the followingspecification, and the devices and means by which they are accomplishedare fully described therein.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a detail side elevation View of a governor embodyingthe features of my in- Fig. 2 is a detail longitudinal sectional viewtaken on line 2 2 of Fig. 3, the rod I being shown in full lines. Fig. 3is a detail cross-section al view taken on line 3 3 of Fig. 1.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and similarletters of reference refer to similar parts throughout the severalviews.

'Referring to the lettered .parts of the drawings, A represents-thevalve-casing. Upon this the governor mechanism is mounted. The

valve-stem is divided into two parts B and O. The part B is connected tothe valve and the part C to the governor mechanism.

The parts of the valve-stem are connected by alever structure. The armor lever D engages the head B of the part B of the valvestem and thelever E the head C of the part 0 of the valve-stem. The lever D is keyedto the shaft F and the lever E is pivoted there- The ends D E of thesearms or levers are bent downwardly, substantially at right angles, and ascrew G is provided by means of which the relative positions of the armsD and E are accurately controlled, and the length of the valve-stem maybe increased or dimin ished as it is desired to increaseor diminish thespeed of the engine, it being apparent that the longer the valve-stemthe less the motion required of the governor-balls to close the valve.

Connected to the screw G by a universal,

forward part of the engine and it is necessary for the engineer. toleave his customary position on the engine to adjust the same. It isintended that the rod I shall be of such length and be in such positionas to be within convenient reach of the engineer without his leaving hisstation. Y

Pivotally supported on the bracket K,

which may be secured in any convenient place on theengine, is abracket-K, the parts being secured together by a rod or shaft r, so thatthe bracket K is free to rock back and forth. On the rod is a collar J,having a downwardlyextending lug pivotally secured to the bracket K bythe pinr. A coiled spring a is provided to put tension upon the rod I,so that it will not be accidentally rotated. The collars which areadjustably secured to the rod I by suitable set-screws, are provided tohold the parts in their proper relation.

The tension-spring holds the rod in its adjusted position, so that it isnot necessary to provide a catch or the like, and prevents thedisplacement by jarring or the bending or sagging of the rod.

It would be possible to make a practical structure without the universaljoint H as connection for the screw G to the rod I. It would, however,require very careful adjustment, which is not necessary in thisstructure. The rod may be placed in any position for convenience of theoperator without any special adaptation. The pivoted bracket K allowsfor any movement which may be necessarily due to the adjustment, andthiswithout strain on any of the parts. the practical operation of engmesforexample, of the traction-engine cl assthat a perfect control of thespeed while in operation is very desirable. By this arrangement of partsit is successfully accomplished. In cases of emergency should thethrottle refuse to operate or a great amount of power be suddenlydemanded a pull on the rod 1 will close the valve or a thrust on the rodwill hold the valve open against the action of the governor.

I have illustrated and described my improved engine-governor in detailin the form preferred by me. I am aware, however, that it is capable ofconsiderable variation in structural details without departing from myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; a screw for adjusting said connections; a rod having asuitable handwheel; a universal joint for connecting said rod to saidscrew; a pivotally supported bracket; a collar J on. said rod pivotallysecured to said bracket; a collar y'adjustably secured on said rod; anda coiled spring arranged between said collars, for the purposespecified.

2. In a speed-regulating device for steamengine governors, thecombination of a Valve with the governor; connections for said valve tosaid governor; a screw for adjusting said connections; a rod having asuitable handwheel; a universal joint for connecting said rod to saidscrew; a pivotally supported bracket; and a collar J on said rodpivotally secured to said bracket, for the purpose specified.'

3. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; a screw for adjusting said connections; a rod having asuitable handwheel; auniversal joint for connecting said rod to saidscrew; a pivotally-supported bracket; and a tension-spring for said rod,for the purpose specified.

4. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; a screw for adjusting said connections; a rod having asuitable handwheel; and a universal joint for connecting said rod tosaid screw, for the purpose specified.

5. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; a screw for adjusting said connections; a rod having asuitable hand- It is also found in wheel; and a pivoted support for saidrod, for the purpose specified.

6. 111a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; means for adjusting said connections; a rod having asuitable handwheel, suitably connected to said adjusting means; apivotally-supported bracket; acollar J on said rod pivotally secured tosaid bracket; a collar 7' adjustably secured on said rod; and a coiledspring arranged between said collars, for the purpose specified.

7. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; means for adjusting said connections; a rod having asuitable handwheel suitably connected to said adjusting means; apivotally-supported bracket; and a tension-spring for said rod, for thepurpose specified.

8. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve tosaid governor; means for adjusting said connections; a rod having asuitable handwheel, suitably connected to said adjusting means, and apivoted support for said rod, for the purpose specified.

9. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; connections for said valve. tosaid governor; means for adjusting said connections; and a rod having asuitable handwheel, suitably connected to said adjusting means, for thepurpose specified.

10. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; means for adjusting saidgovernor, whereby said valve is controlled; a rod having a suitablehand-wheel connected to said adjusting means by a universal joint; andsuitable means for supporting said rod, for the purpose specified.

11. In a speed-regulating device for steamengine governors, thecombination of a valve with the governor; means for adjusting saidgovernor,whereby said valve is controlled and a rod having a suitablehand-wheel connected to said adjusting means by a universal joint, forthe purpose specified.

12. In an engine-governor, the combination of a speed-adjustingmechanism; a screw for adjusting said mechanism and a rod connected tosaid screw, for the purpose specified.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
